All my cars are white.
In the Florida sun, no other color makes sense. Also, since white pigment is based on extremely durable TiO2, and reflects most of the light that hits it, it remains cooler and degrades less in sunlight. I have a 19-year old Sentra which I park outside, wash once a month and wax twice a year. It's got dents and even a little rust, but it still buffs up to a mirror shine.
